Two-circuit gas hob and method for preventing a nozzle fire in a two-circuit gas hob

摘要

The invention relates to a two-circuit gas cooker (9) with a dual-circuit burner (10), which comprises a simmer nozzle (13) and a main nozzle (12), each with associated gas connections (14, 15), with a burner head (16), which simmer openings ( 22) and main openings (27), with a burner cover (19) for at least partially covering the burner head (16), with an adjusting device (31) with which optionally a gas supply only to the Simmer nozzle (13) or Simmerdüse (13) and to the main nozzle (12) is adjustable. In order to prevent soot formation as a result of a nozzle fire, a detection device (45) is proposed with which a fire in the area between the main nozzle (12) and burner cover (19) can be detected. The invention also relates to a method for preventing a nozzle fire between the main nozzle (12) and the burner cap (19) of such a dual-circuit gas cooker (9).
